I play women's football and coach high school guys football. Football is one of the most teamwork-dependent sports out there. Everyone has to be doing his job every single play. There's no way for one player to carry the team.
Before I started coaching guys' football, I had heard consistently from other coaches in my women's league that women are way easier to coach than men in the game of football. Reasons given included less attitude, less individualism, less ego, more willing to work together, etc. When I started coaching high school ball, this was exactly the case. So much of my time was wasted beating the individualism out of these boys and getting them to play for each other, not themselves.
Maybe it's that football attracts a certain type of male. But I think women might be more naturally disposed to working on a team than men on average.
